I just fixed a race condition in the auth middleware using a mutex. Verify this is actually done and won't break prod.
Your agent does
Verification Plan:
- Evidence: Run 'go test -race ./auth/...' 100x to prove zero flakes.
- Regression: Test login flow with slow network simulation.
- Cache Trap: Force logout and verify JWT invalidation is immediate.
- Edge Case: Trigger concurrent login and password reset calls.

About this skill
'Should work now' is the most expensive sentence in software — it means the change was reasoned about, not observed, and the next person to touch this code will pay for that assumption. This skill builds the verification protocol for your specific change: the exact commands to run, the outputs to observe, the edge cases to test manually, and the signals that confirm the fix didn't introduce a regression. It treats verification as a first-class artifact, not an afterthought. Use it before you close any ticket — give it your change, your environment, and what you've already tested; it returns the complete verification checklist that lets you say 'done' and mean it.
Changelog
- v1.1LatestJun 26, 2026
Rewrote the skill body with real, expert content. Every section now carries concrete verification method (defining observable 'working', evidence over inference, verification design per change type, cache & stale-version traps and how to defeat them, environment verification, regression & neighbour checks, negative-testing the fix, building an evidence trail, independently verifying AI-agent 'done' claims by re-running, and upgrading the team Definition of Done). Replaced the generic placeholder sections.
